How to define climate justice

The article argues that we need a concrete, simple, well-justified, and global concept for climate justice, and then suggests such a concept. It starts with the abstract idea that nobody should use more than what provides others, both those living now and in the future, with the same opportunity to live on a sustainable planet. This idea is then made concrete by the use of the concept of a global hectare, which is further transformed into the currency of climate dollars in order to establish a clear understanding of what constitutes fair and sustainable behavior. The suggestion is defended against a long list of objections.
